Answer:
power is the rate at which work is done
Explanation:
Which of the following correctly expressed power
-power is work
- power is the rate at which work is done
- power is determined by mass
- power is determined by work in mass
We know that work done is the force applied in a given direction or the product of force and distance. When force is applied on an object and no distance is covered , we say that is zero work.
Power is when work is done per time. Power is measured in watt
Power=force x distance/time
Power(W)=work done/time
We can electrical power, mechanical power. So far a particular work is done per time.
